[0002] In the production of paper carton beverages, the beverage cap is a crucial component, playing a key role in maintaining the quality of the beverage inside and preventing leakage. During storage, it's essential to prevent impurities from entering and evaporating; the sealing performance of the beverage cap directly determines the preservation quality. Currently, the production of paper carton beverage caps typically utilizes injection molding. However, in traditional injection molding production, the threaded demolding of the beverage cap relies heavily on manual operation. This not only results in low demolding efficiency, significantly impacting production progress, but also makes it easy to damage the cap due to improper handling, leading to a lower product yield.

[0003] Based on the above, this utility model proposes a paper carton beverage cap demolding mold, which can effectively solve the above problems. Utility Model Content

[0008] The lower mold assembly consists of a lower mold base, a first lower template, a second lower template, a third lower template, and a fourth lower template, which are fixedly connected from bottom to top. Multiple rotating bearings, evenly distributed at equal angles, are installed inside the first and second lower templates. Each rotating bearing is rotatably connected to a first rotating shaft. The bottom end of the first rotating shaft is rotatably connected to the lower mold base, and a forming fixing sleeve is installed at the top end of the first rotating shaft. The forming fixing sleeve engages with the forming cavity to form the forming gap for the paper carton beverage cap.

[0009] According to the above technical solution, as a further preferred technical solution, the lower mold assembly is further provided with a demolding mechanism; the demolding mechanism includes a drive motor, the drive motor is mounted on the first lower mold plate, the output end of the drive motor passes through the first lower mold plate and is fixedly connected to a first sprocket, the first sprocket is connected to a second sprocket through a chain, the second sprocket is fixedly connected to a second rotating shaft, the bottom end of the second rotating shaft is rotatably connected to the lower mold base, the top end of the second rotating shaft is fixedly connected to a first gear, the outer periphery of the first gear is meshed with multiple second gears, and the second gears are fixedly connected to the first rotating shaft.

[0013] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0014] This utility model provides a mold for releasing paper carton beverage caps. By incorporating a glue-feeding block and its internal glue-feeding groove, inlet, and outlet within the upper mold assembly, it achieves uniform distribution of injection molding material within the mold, ensuring the molding quality of all parts of the product. Simultaneously, the arrangement of multiple gating channels and molding cavities allows the injection molding material to smoothly fill the molding cavities and cooperate with the molding retaining sleeve of the lower mold assembly to form the molding gap for the paper carton beverage cap, thereby precisely shaping the paper carton beverage cap.

[0015] By setting up a demolding mechanism, the rotation of the first rotating shaft and the forming fixed sleeve is realized through the interaction of the drive motor, the first sprocket, the second sprocket, the second rotating shaft, the first gear and the second gear. This separates the formed paper carton beverage cap from the external thread at the top of the first rotating shaft, eliminating the threaded connection between the two. This makes it easier for the paper carton beverage cap to be removed from the mold, which greatly facilitates the workers' material handling operations and effectively saves material handling time.

[0022] A paper carton beverage cap demolding mold includes an upper mold assembly and a lower mold assembly, wherein:

[0023] The upper mold assembly includes an upper mold base 1, a first upper mold plate 2, and a second upper mold plate 3, which are fixedly connected from top to bottom. A positioning ring 4 is provided at the top center of the upper mold base 1, and a glue inlet channel 101 corresponding to the positioning ring 4 is provided inside the upper mold base 1. A cavity 201 is opened at the top of the first upper mold plate 2, and a glue conveying block 5 is installed inside the cavity 201. The glue conveying block 5 has a glue conveying groove 501 inside, and a glue inlet 502 is provided at the top center of the glue conveying block 5 directly below the glue inlet channel 101. Multiple glue outlets 503 are evenly distributed at the bottom of the glue conveying groove 501. Multiple pouring channels 301 are opened at the first upper mold plate 2 and the second upper mold plate 3, which are directly opposite to the glue outlets 503. Multiple molding cavities 302 communicating with the pouring channels 301 are opened on the lower surface of the second upper mold plate 3.

[0024] The lower mold assembly consists of a lower mold base 6, a first lower template 7, a second lower template 8, a third lower template 9, and a fourth lower template 10, which are fixedly connected from bottom to top. Multiple rotating bearings 11, evenly distributed at equal angles, are installed inside the first lower template 7 and the second lower template 8. Each rotating bearing 11 is rotatably connected to a first rotating shaft 12. The bottom end of the first rotating shaft 12 is rotatably connected to the lower mold base 6. A forming fixing sleeve 13 is installed at the top end of the first rotating shaft 12. The forming fixing sleeve 13 engages with the forming cavity 32 to form the forming gap of the paper carton beverage cap 21.

[0025] This invention achieves uniform distribution of injection molding material within the mold by incorporating a glue-feeding block 5 and its internal glue-feeding groove 51, glue inlet 52, and glue outlet 53 within the upper mold assembly, thus ensuring the molding quality of each part of the product. Simultaneously, the arrangement of multiple gating channels 301 and molding cavities 302 allows the injection molding material to smoothly fill the molding cavity 302, cooperating with the molding fixing sleeve 14 of the lower mold assembly to form the molding gap of the beverage carton cap 21, thereby precisely shaping the beverage carton cap 21.

[0026] Furthermore, in another embodiment, the lower mold assembly is further provided with a demolding mechanism; the demolding mechanism includes a drive motor 14, which is mounted on the first lower mold plate 7. The output end of the drive motor 14 passes through the first lower mold plate 7 and is fixedly connected to a first sprocket 15. The first sprocket 15 is connected to a second sprocket 16 via a chain. The second sprocket 16 is fixedly connected to a second rotating shaft 17. The bottom end of the second rotating shaft 17 is rotatably connected to the lower mold base 6. The top end of the second rotating shaft 17 is fixedly connected to a first gear 18. The outer periphery of the first gear 18 is meshed with multiple second gears 19. The second gears 19 are fixedly connected to the first rotating shaft 12. The top outer periphery of the first rotating shaft 12 is provided with an external thread 121.

[0027] By setting up a demolding mechanism, the first rotating shaft 12 and the forming fixing sleeve 13 are rotated through the interaction of the drive motor 14, the first sprocket 15, the second sprocket 16, the second rotating shaft 17, the first gear 18 and the second gear 19. This allows the formed paper carton beverage cap 21 to be separated from the external thread 121 at the top of the first rotating shaft 12, eliminating the threaded connection between the two. This makes it easier for the paper carton beverage cap 21 to be removed from the mold, greatly facilitating the workers' material handling operations and effectively saving material handling time.

[0028] Furthermore, in another embodiment, the inner wall of the molding cavity 302 is provided with a plurality of anti-slip strips 303 evenly distributed at equal angles.

[0029] By setting anti-slip strips 303, on the one hand, an anti-slip structure is simultaneously formed on the outer side of the molded paper carton beverage cap 21, making it easier for users to open the paper carton beverage cap 21; on the other hand, during the injection molding process, it prevents the paper carton beverage cap 21 from rotating simultaneously when demolding, thus facilitating smooth demolding.

[0030] Furthermore, in another embodiment, a plurality of positioning posts 20 are fixedly connected inside the chamber 21.

[0031] By setting the positioning column 20, the flow block 5 can be accurately positioned, thereby ensuring the accurate connection between the outlet 53 and the pouring channel 32, so that the injection material can flow smoothly according to the design requirements, ensuring the molding quality and consistency of the product.
